ATTACHMENT FR1HYDROMETER UNITS.

Application enana-c11- s, 192e.` serial natascia,

rubber bulb at the other end for suckingcthe electrolyte into the tube or barrel, Within which is carried the hydrometer perse.

in the operation of such' a device there is practically always some drip from theattachment on the end of theptub'e or barrel, which is ordinarily in the form of a rubber tube and this drip I have found, has caused a lot of trouble as one drop of the electrogravity of from twelve 'to thirteen hundred, will ruin a piece of wearing apparel in very short order. c n

My invention is therefore directed `to means for preventing this drip from comin@ in contact with the users person or appare and a further object ist@ provide a device that will accomplishthe main obj ect, which is Vcheap to manufacture and readily applicable to various designs `of hydrometer devices, it being understood that throughout this specification, the barrel or glasstube,

` which is usually used, with 'its associated bulb and hydrometer, is referred to as a hydrometer unit. j p

invention will Vbe readily understood by reading the following specification taken in connection with the annexed drawing wherein, Figure l, isa view of a hydrometer the hydrometer unit cornhydrometer 3. v, l

'My improvement comprises an attachment preferably lof soft rubber moulded in one piece, and has'a part fl, shown in the nature of a plug, which is adapted to close the end .f of the barrel l, of the hydrometer unit.v A

flange is provided for assisting in applying the attachment. .Extending downward from the part 4l, Aand flange 5, 1s a pair of alims 6 and 7, at the lower end of which is carried a 'receptacle 8, having a cavity 9, which is Anormally in alignment with 'a' stem 1 0, that is securely attached to the part-t;V The Stem l0, is preferably lof some stronginsulating l material that will not be attacked by elecdrawn by forcing the air out of the bulb 2,'V

before the insertion of the stem 1,0, inA the batte-ry cell. On withdrawal of the stem 10, during the act of raising the hydrometer unit up, in Aorder to read the hydrometer7 the arms 6 and 7, preferably being of soft Yrubber andhavi'ng considerableresiliencev automatically carry the receptacle 8, back vto its, normal position as shown in Figure 1, whereby the cavity 9, is below and substantially-in alignment with the passage 171, of the stem 10, so that anyl drip coming from the stem will be caught bythe cavity 9, which is so formed that a' drop ortwo of electrolyte which may'v pass into it during the reading of the hydrolmeter will not run' out, when the electrolyte in the shell l', and' the -bulb 2, is being ireturned. to the battery cell.

After the hydrometer unit has beenr used end, and within the shell is carried the usual i ice as above described, the attachment may be washed off 0r wiped olf, and the whole unit returned to its carryingk case. v

It will be apparent that my invention is susceptible of certain changes in detail without departing from the spirit of invention, and the scope of the appended claims, for example the part l, which isintegral with the part 6 and 7 may lit on over the member l, and the claims are intended to be broad enough to Cover either or both forms.

Y Having thus described my inventionwhat I claim is:

l. An attachment for a hydrometer receiving barrel comprising: a closure for one end of the barrel, a hollowstem carried by said closure and adapted to be inserted into a vessel containing a liquid, the specific gravity of which is desir-ed to be measured, means attached to said kclosure and extending downwardly therefrom and a recepticle supported by said means substantially below the stem, said means being adapted to be moved so as to carry the receptacle away from its position below the stem so said stem may-be inserted into said v-essel.

2. An attachment for a hydrometer receiving barrel comprising: a closure for one end of the barrel, a hollow stem carried by said closure and adapted to be inserted into a vessel .containing a liquid the specificV gravity of which is desired to be measured, a pair of flexible arms extending downwardly from said closure, a receptacle carried by said arms and normally below said stem, said arms being adapted to be moved so said receptacle is carried from its normal position below the stem when the same is to be inserted into said vessel.

3. An attachment for a hydrometer receiving barrel comprising: a closure for one end of the barrel, a hollow stem carried by said closure and adapted to be inserted'into a vessel containing a liquid the specific gravity of which is desired to be measured, a pair of resilient arms attached to said closure and normally extending in avertical direction downwardly one on either side of said stem, a receptacle carried by said arms below the end of the stem, said arms being adapted to be bent sidewise so as to carry the receptacle out of the path of movement of the stem for the purpose described, said resilient arms also acting to automatically move the receptacle baclr to normal position under the stem, when the stem is withdrawn from the vessel.

4. An attachment for a hydrometer receiving barrelcomprising: a closure for one end of the barrel, a hollow stem carried by said closure and adapted to be inserted into a vessel containing a liquid the specific gravity of which is desired to be measured,

means attached to said closure and extending downwardly therefrom and a receptacle supported by said means substantially below and in alignment with the stem, said means and receptacle adapted to be moved sidewise so said stem may be inserted into said vessel, said means functioning on withdrawal of the stem from the vessel to carry the receptacle automatically back to normal position under the stem.

V5. VAn attachment yfor a hydrometer receiving barrel comprising: a soft rubber closure for one end of the barrel, a hollow rigid stem carried by said closure and adapted to 'be inserted into a vessel containing a liquid the specific gravity of which is desired to be measured, a pair of spaced soft rubber arms integral with said part, and extending downwardly below .said stem and ajreceptacle preferably of soft rubber and integral with said arms carried thereby below the end of said stem.

6. An attachment for a hydrometer receiving barrel comprising: a soft rubber closure for one end of the barrel, a hollow stem of rigid insulating material carried by said closure and adapted to be insert-ed into a vessel containing a liquid the specific gravity of which is desired to be measured, a pair of spaced soft rubber arms integral with said Vpart and extending downwardly therefrom on opposite sides of the stem and a soft rubber cup moulded integral with said arms and normally held below the .stem but adapted to be moved aside by bending said arms by the act of insertion of said stem into the vessel and further adapted toy return to normal position for the purpose described when the stem is withdrawn from the vessel.

7. An attachment for a hydrometer receiving barrel comprising: a one piece device of soft rubber and a rigid hollow stem of insulating material, said one piece device having a closure to engage the hydrometer receiving barrel and having means attached to said closure and extend- `ing downwardly from the closure` said ture.
